Home Folder total endpoint problem

i was wondering why when we logon to the SEPM console via web or from the server itself, the total endpoints displayed is not the REAL total endpoints installed from the server.. This is regardless on what account is we are using.

We have a current machines installed with 500 clients but from the home tab, sometimes it says the corrent number, sometimes lesser than 500. No endpoints is being deleted or uninstalled.

if you do from SEPM the backup will be saved under backup folder. From SQL you can back it up to anyware. The home tab shows only 24 hours info only so most of the times it may not be accurate while few servers will be off / not communicating in that 24 hour interval
